Nu-Calgon Cal-Blast II is a high-performance, non-flammable aerosol condenser coil cleaner designed to tackle the most stubborn, oily deposits. It is particularly effective for HVAC systems located in kitchen environments, where grease and resistive residues frequently plug coils. Engineered with high solvency power, this cleaner works by effectively separating unwanted materials from finned surfaces without the need for a rinse, evaporating completely to leave no residue behind. The formula features a pleasant citrus scent and is safe for use on electrical equipment due to its high dielectric strength, ensuring it will not cause short circuits. Beyond its powerful cleaning capabilities, Cal-Blast II is formulated for convenience and compliance. As a quick-drying aerosol, it minimizes maintenance downtime and provides a blasting spray that reaches deep into the coil for maximum cleaning impact. The product is also environmentally conscious, fully meeting California VOC regulations. Whether you are performing routine maintenance or deep cleaning a heavily soiled system, Cal-Blast II offers a professional-grade solution to restore coil efficiency and ensure optimal heat transfer in demanding settings.
